T0 ALL WHOM IT MAY CVONCERN:

Be it known that I, CHARLES B. SMITH, of Springfield, in the county of Sangamon, and State of Illinois, have invented a new and useful Imprvement in Spring-Seats; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of'this specification, in which-- Figure 1 represents a sectional elevation oi' my improved seat, and I Figure 2 represents a plan view ofthe bottom of the sam e.

Similar letters of reference indicate like parts.

The object of this invention is to provide improved spring-seats of more uniform character and durable arrangement than any now in use. I

It consists in forming the main portion ofthe bottom of the seat of thin strips of metal, laid longitudinally and transversely, and riveted at the intersecting points, the ends of which strips are provided with hooks, which hook into and are supported by loops projecting from double-coiled springs secured to rods or bars connected to the base or frame of the seat. n

A represents the main portion of the spring-bottom, which is composed of strips of sheet metal, arranged transversely and longitudinally of the seat, Aso as to cross each other at right angles, and riveted at the points of intersection.

The ends of the strips are provided with hooks, which take into the loops B of the douhle-coiled springs C, suitably arranged upon the bars or rods D, connected to the frame of the seat.

By this arrangement the springs are not so liable to damage, by reason of undue strain or weight falling at any time upon 4them singly. The strips of metal being connected together as described, `will communicate so much ofthe strain to other springs as to relieve any one from the strain sueiently to prevent such damage.

Another important advantage of my improved arrangement is, that the springing portion of the `seat presents such a smooth and uniform upper surface, thatI a considerably. less amount of smiling-material is required to produce seats of equally/*good finish with others of ordinary construction, where more of the said` material is required -to be used.

My improvement may be used with advantage for couches for sleeping-cars, steamboat-berths, and for other purposes, but it is more particularly designed for use as spring-seats for railroad-cars, carriages, te

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The improved spring-seat bottoms, composed of the hooked strips A, riveted together as described, in combination with the double-coiled springs, supported on the frame, and provided with the loops B, substantially as and for the purpose described.

CHARLES B. SMITH.
